When it comes to custom CNC machining, most people don't know about it, as it is associated with the technical field. Computer numerical control machining is a necessary manufacturing process. The custom CNC Machined parts produced by this process play an essential part in ensuring your entire machine works efficiently. And thanks to the precise production of various parts.

Custom CNC machining produces exact parts that are impossible in manual processing or anywhere else. It doesn't limit CNC Machining; instead, it takes different forms of CNC Machining, including CNC turning, EDM, and CNC milling, which a particular company offers. 

Now people are behind customizable and precise CNC machined parts, and luckily, through CNC turning, CNC milling & CNC machining, it's possible to get the desired Machined parts. People need custom CNC Machined parts when they want special requirements for common parts. It meets the customer's needs thoroughly. Now the creation of precise parts with CNC Machining services and other CNC forms or CNC machine tools (such as CNC milling services, CNC turning) is available. Let's learn more about CNC production machining, its working process, advantages, considerations, materials, and so on. Just stay tuned with us.

How to Work

To get CNC machining work, you need a digitalized computer (by using a CAD file) that automates, controls, and monitors the movement of the industrial machine. In large industrial plants, the computer is mostly installed in the machines. 

The exact movements which the code controls always depend on the type of CNC machine that is being used. Let's learn it deeply in different steps.  

  • First of all, the CAD model or program is installed in the CNC machine. 
  • Then the data is processed by singing in it and preparing the set of commands sent to the driving system. 
  • Now the driver system observes the commands sent by the CNC machine and controls the velocity and motion of the machine tool. 
  • Then the feedback system observes the velocity and position measurement and then sends these signals to the MCU of the CNC machine. 
  • Finally, a display unit shows the working process, program, commands, plus other essential data. It is known as the eye of the system. 

Types Of Custom CNC machining

There are some types of CNC machining that are introduced in the modern market. Let's explore them one by one.

5-Axis CNC Machining Centers

5-axis machining provides infinite possibilities as to the part shapes and sizes you can effectively process. The term "5-axis" explains the number of directions where the cutting tool can move in all positions. On a 5-axis machining center, all the cutting tools move across the X, Z, and Y along with linear axes plus rotates on axes A and axes B to reach the workpiece from all sides direction. In other words, you can even process five sides of the given part in a single setup to achieve custom CNC Machined parts.

Benefits of 5-axis Machining:

  • Complex Designs 
  • Rotational Accuracy
  • Faster Material Removal
  • Better Surface Finishes

Prototype Plastic Machining

Depending on the geometry, CNC machining would be one of the fastest and most reliable methods of creating plastic prototypes. CNC machines usually use multiple cutting tools along with cutter paths that are optimized for the particular cut intended in the process of carving or achieving a 3D model directly from a solid block of plastic. 

This particular plastic CNC machining technology is highly & extremely versatile, complex, feasible for a vast range of product sizes, capable of having threaded features, plus particularly suited to prototypes that require tight tolerances. Fast turnaround time for all completed models is possible with the suppliers who specialize in prototype machining. Rapid Prototyping CNC machining service is extremely valuable & reliable as a product geometry check before initiating full production injection molding tooling.

There are also various advantages that CNC machining holds over 3D printing technology, one of which is the mechanical quality plus the available range of thermoplastic materials. Parts that are CNC machined become bestow improved structural integrity over plastic parts as well, which is essential when producing functional prototypes. Typically, this creation method is always used to produce plastic prototypes that will be tested under the same conditions as injection molded parts. 

Metal Machining

Metal machining is a well-known form of a manufacturing process that is used in the production of metal parts, machinery, or tools. It involves versatile processes to ensure & get the final product's desired design in terms of hole diameter, finishing, shape, size, and texture. There are also additional materials which are used in the machining process depend on the following: Plastics, rubber, and paper goods. 

Wood Machining

Wood Machining explains working with versatile tools like a shaper, double-ended tenner, router, four siders where the employee ensures grinds will cutters and/or sets up and/or a router and/or a shaper hand which works freehand.

Unlike manual work, CNC machines are able to work continuously without compromising & plunging quality. Therefore, flexibility and safety are highly important in the wood machining process. 

Advantages Of Custom Machining

CNC machining has plenty of advantages under its belt, and no sector is an exception to it. Through CNC machining advantages, you get what you want without zero alternation in the exact sample. Here we will highlight some prominent advantages as you should be familiar with them. 

High Precision and High-Quality Parts

CNC machining always allows the creation of demanding applications in all sectors. Even with small diameters & unique features on a particular part, and the high precision power of CNC production allows you to get precisely & exactly what you need. In addition, the production machine regularly allows the production of similar & exact parts over and over unless the last piece you order

Timely Production

Custom CNC Machined Parts always help to remove blocks of raw materials unless you get the desired shape. A computer manages the production of Machined Parts and ensures the speed is according to a set limit. Considering the machine is modified to follow specific procedures, it is indeed hard to encounter mistakes that could lead to repeating the process. Further, a company that provides CNC machining services consists of professional CNC engineers having experience in producing plenty of parts plus translating to a quick turnaround.


When a product is nicely designed, it is hardly found in multiple stores. If you find it in rare stores, then it is expensive. By choosing custom machining services, you remove the possibility of spending more budget than you should & still get a high-quality product.

Considerations For Design CNC Machining 

CNC machines are an excellent modern-day technology that provides a wide range of possibilities for accurate parts, but if you set a good design, then you can achieve the end product. So to achieve the best end-products, you mind some considerations for part geometry. These are some basic design guidelines and corresponding tools you should follow throughout the post-processing.

Inner Edges

Inner Edges are also named sharp edges in design, so they are one-third of the cavity depth, and for surface finish, the corner radius works perfectly instead of a 90-degree angle. But if someone wants a 90-degree angle, then they should use a T-bone undercut. 


Holes require special tooling because they are tricky to handle. Holes can take drilling or CNC mills tools. If higher accuracy is needed, the diameter of the hole should be less than 20mm, and non-standard diameters can be Machined with end diameter. 

Thickness of Wall

Thin walls decrease the wall thickness and shorten the material stiffness of soft metals plus give low friction; thus, low volume production runs. In addition, in the case of plastic as well as other wear resistance, corrosion-resistance, and high thickness of the wall can mitigate the stress in custom CNC Machined Parts.
